An Introduction to Tissue Engineering and the Most Widely Used Scaffolds

In today’s world, humankind is exposed upon a wide spectrum of diseases and tissue damages,
which some of them are untreatable with current medical approaches. The untreated damaged tissues
encompasses a widespread of destroyed parts with loss function in which natural repair mechanisms are not able
to reconstruct them. Therefore, remedy for these lesions is related to a branch of medical sciences called
regenerative medicine. One of the tools in regenerative medicine is transplantation of tissue-like structures via
tissue engineering. We searched several databases such as PubMed, Scientific Information Database (SID),
Springer, Medline, Magiran, ScienceDirect, and Sivilica, and used Google Scholar search engine to find the
articles in this issue. Different researches and clinical results show that with the help of tissue engineering,
structures similar to natural tissues for repair can be designed. These structures are made up of three parts of
scaffold, cell, and growth factors. In the construction of these structures, the design of ideal scaffold with the
desired properties and mechanical strength is important, depending on the type of material and method of its
construction. Regenerative medicine and tissue engineering are successful and necessary in repairing or replacing
damaged tissues
